Description

Fan cable twisting protection device

Technical Field

The utility model relates to a cable protection device, concretely relates to cable protection device is turned round to fan.

Background

The wind turbine is a wind driven generator, and the wind direction needs to be continuously tracked during normal operation to obtain the maximum wind energy. The fan yaw system can be automatically started when the monitored cabin deviates from the wind angle, and the position of the cabin is changed. At the moment, the cable from the cabin to the tower is twisted, and the maximum twisting angle in design is +/-700 degrees. A set of device is needed to protect the cable in the twisting process, and the cable is prevented from scattering, knotting and abrasion.

The existing twisted cable protection devices mainly have two types: one is to adopt a rubber coating to block the friction between the cable and the limiting ring; the disadvantages are as follows: the rubber is not easy to fix and fall off, and generates larger heat in the friction process to be unfavorable for the heat dissipation of the cable, and meanwhile, the rubber is fast in consumption, short in maintenance period and uneconomical; the other type adopts the scheme that a limit point is added, the shaking of the cable is limited to the maximum extent, and meanwhile, a rubber skin is used in an auxiliary mode to protect the cable; however, the increase of the limit points can only limit the shaking of the cable, and the essence of the sliding friction and the collision between the cable and the limit ring cannot be changed, so that the improvement is awaited.

Therefore, there is a need in the art for a new solution to the above-mentioned problems.

the rotary disk is clamped in a track groove of the fixing ring and can freely rotate in the fixing ring, the rotary disk is of a split structure and is composed of multiple identical assembling pieces, a rotary disk connecting lug is arranged on each assembling piece, threaded holes used for connecting two adjacent assembling pieces are formed in the rotary disk connecting lug, the rotary disk is provided with a circular cable channel and a plurality of oval cable channels, the circular cable channel is located in the center of the rotary disk, and the oval cable channels are evenly distributed on the periphery of the circular cable channel.

Further, the number of the oval cable channels is 3-6.

Preferably, the number of the plurality of oval cable passages is 4.

Furthermore, the semi-ring and the boss are of an integrated structure.

Adopt above-mentioned technical scheme the utility model discloses following beneficial effect can be brought:

the utility model discloses a gu fixed ring and rotary disk form through the same part combination of structure more than two separately, can install the operation under the condition that the cable was laid in advance to it is extremely convenient, simultaneously to maintain the change a plurality of cable passageways that have can come the abundant isolation of pencil, do not influence the radiating effect of cable.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to the attached drawings 1, 2, 3 and 4, the fan twisting cable protection device comprises a fixing ring 1 and a rotating disc 2, wherein the fixing ring 1 and the rotating disc 2 are both made of composite wear-resistant polymer materials, the fixing ring 1 is of a split structure and is formed by connecting two half rings with the same structure, a track groove is formed in the inner surface of each half ring, a boss 1-3 is arranged at the bottom of each half ring, the half rings are connected with the bosses 1-3 through bolts, and the bosses 1-3 are used for being in butt joint with an iron ring on a fan so that the fixing ring 1 is firmly fixed with the iron ring on the fan; fixing ring connecting lugs 1-1 are arranged at two ends of the semi-rings, and threaded holes 1-2 for connecting the two semi-rings are formed in the fixing ring connecting lugs.

The rotating disc 2 is clamped in a track groove of the fixing ring 1, the rotating disc 2 can freely rotate in the fixing ring, the rotating disc 2 is of a split structure and consists of a plurality of assembly pieces 2-4 with the same structure, each assembly piece 2-4 is provided with a rotating disc connecting lug 2-3, each rotating disc connecting lug 2-3 is provided with a threaded hole for connecting two adjacent assembly pieces, the rotating disc 2 is provided with a circular cable channel 2-1 and a plurality of elliptical cable channels 2-3, the circular cable channel 2-1 is positioned at the center of the rotating disc, the elliptical cable channels 2-2 are uniformly distributed at the periphery of the circular cable channel 2-1, the rotating disc 2 is used for dividing a plurality of cables to play a role of preventing the cables from being worn, and according to the difference between the diameter of an iron ring on the fan and the number of the cables, the number of the cable channels formed in the rotating disc 2 is 3-6, and when the cables are twisted, the rotating disc 2 can rotate and slide in the groove rail of the fixing ring 1 according to the twisting direction of the cables, so that the abrasion phenomenon caused by the fact that the cables contact the iron ring and the cables is avoided.
